At a glance – gustier than usual this morning.
As someone who cycles to work most days, I keep a pretty close eye on the weather. One thing I like to know is which way the wind is blowing – a strong headwind means I should maybe opt for the road bike, not the cruiser. Home Assistant has a ton of weather platforms – and the Dark Sky one that I prefer tracks wind direction. The only problem is it returns the direction in degrees, which is meaningless to me.
See below for a template sensor that will convert degrees to a human-readable cardinal direction.
This assumes you have your sensors broken out into a separate YAML file.
sensors.yaml
# Convert the Wind Direction from degrees to cardinal
- platform: template
sensors:
friendly_wind_direction:
friendly_name: 'Wind Direction'
value_template: >-
{%if states.sensor.dark_sky_wind_bearing.state | float<=11 %}N
{% elif states.sensor.dark_sky_wind_bearing.state | float>348 %}N
{% elif states.sensor.dark_sky_wind_bearing.state | float<=34 | float>11 %}NNE
{% elif states.sensor.dark_sky_wind_bearing.state | float<=56 | float>34 %}NE
{% elif states.sensor.dark_sky_wind_bearing.state | float<=79 | float>56 %}ENE
{% elif states.sensor.dark_sky_wind_bearing.state | float<=101 | float>79 %}E
{% elif states.sensor.dark_sky_wind_bearing.state | float<=124 | float>101 %}ESE
{% elif states.sensor.dark_sky_wind_bearing.state | float<=146 | float>124 %}SE
{% elif states.sensor.dark_sky_wind_bearing.state | float<=169 | float>146 %}SSE
{% elif states.sensor.dark_sky_wind_bearing.state | float<=191 | float>169 %}S
{% elif states.sensor.dark_sky_wind_bearing.state | float<=214 | float>191 %}SSW
{% elif states.sensor.dark_sky_wind_bearing.state | float<=236 | float>214 %}SW
{% elif states.sensor.dark_sky_wind_bearing.state | float<=259 | float>236 %}WSW
{% elif states.sensor.dark_sky_wind_bearing.state | float<=281 | float>259 %}W
{% elif states.sensor.dark_sky_wind_bearing.state | float<=304 | float>281 %}WNW
{% elif states.sensor.dark_sky_wind_bearing.state | float<=326 | float>304 %}NW
{% elif states.sensor.dark_sky_wind_bearing.state | float<=348 | float>326 %}NNW
{%- endif %}

Thanks I did this in my other automation software before “XTension” for the Mac but forgot to transfer it to Home Assistant.
Thank you, this helped a ton. I got also added this to my HADashboard and it makes it much easier to read.
I walk and bus to work so I also need to know the weather before I leave for the day. I appreciate your work, this also helped me clean up my sensors as I did need to create the sensors.yaml.
Thanks.
Great code, thank you! You can also create a variable, and use that variable inside the conditions instead of having `states.sensor.dark_sky_wind_bearing.state | float` in every condition. Something like below:
“`
value_template: >-
{% set value = states.sensor.dark_sky_wind_bearing.state | float %}
{%if value 348 %}N
{% elif value 11 %}NNE
{% elif value 34 %}NE
{% elif value 56 %}ENE
{% elif value 79 %}E
{% elif value 101 %}ESE
{% elif value 124 %}SE
{% elif value 146 %}SSE
{% elif value 169 %}S
{% elif value 191 %}SSW
{% elif value 214 %}SW
{% elif value 236 %}WSW
{% elif value 259 %}W
{% elif value 281 %}WNW
{% elif value 304 %}NW
{% elif value 326 %}NNW
{%- endif %}
“`
That’s great, thanks for the tip!
